Up to 4,000 randomly sampled listings are plotted so hovering stays responsive. Tick “Log price scale” to spread out the lower-priced cars.

Interactive Visualisation 2 – Price by Year of Manufacture

Mean (average) price is shown by default, as in the static chart. Switch to Median to see how a small number of very expensive vehicles pull the mean upwards. Click New or Used in the legend to show or hide each line.
